The most radical thing about Simplifyber’s shoe isn’t that it’s made from plants. It’s that it was never a piece of cloth. The upper debuted at Paris Fashion Week in September 2024, a collaboration with the Danish brand Ganni, and it arrived fully formed from a mold, bypassing the entire textile supply chain of spinning, weaving, cutting, and sewing [simplifyber.com/about, 2026]. For a fashion industry that measures its environmental impact in billions of gallons of water and mountains of scrap fabric, that’s the kind of unit economics that gets attention.
Simplifyber, a Raleigh-based startup, has developed a process it calls “additive manufacturing for soft goods.” They start with a cellulose slurry,a liquid derived from wood pulp, recycled paper, or textiles,inject it into a 3D mold, and out comes a finished product: a shoe upper, a handbag panel, or a car interior component [Perplexity Sonar Pro Brief]. The material, branded as Fybron, is 100% bio-based and fully biodegradable, and the company claims the associated CO2 emissions are 33 times lower than those of a traditional shoe upper [simplifyber.com, 2026]. It’s a bet that the path to decarbonizing fashion isn’t just a better fiber, but a complete rewrite of the factory floor.
A wedge into the supply chain
The company’s wedge is simple, if technically audacious. Traditional apparel manufacturing is a waterfall of waste. Fabric is woven in bulk, cut into patterns (losing up to 15% as scrap), and then assembled. Simplifyber’s process consolidates those steps into one. By dyeing the slurry before molding, they also claim to reduce water use and pollution by up to 95% compared to conventional dyeing [Perplexity Sonar Pro Brief]. For brands, the pitch isn’t just sustainability; it’s simplification. A single-step, on-demand manufacturing process could compress lead times and inventory risk, a powerful proposition in a sector choked by overproduction.
Their initial focus on shoe uppers is strategic. Footwear is a complex assembly of many materials, and the upper is often the most visible, brand-defining component. Landing a showcase at Paris Fashion Week with Ganni provided a high-design proof of concept. The company says it is now running pilot projects with unnamed Fortune 500 brands for biodegradable shoe uppers, handbags, and car interiors [Perplexity Sonar Pro Brief].
The team and the pulp connection
Simplifyber was founded in 2021 by Maria Intscher-Owrang, the CEO, and Phil Cohen, the COO. Intscher-Owrang is a former luxury designer with over two decades in fashion, a background that informs both the aesthetic demands and the supply-chain frustrations the technology aims to solve [Perplexity Sonar Pro Brief]. Cohen brings entrepreneurial and operational experience to handle commercialization and scaling.
The investor roster tells a story about the supply chain being targeted. The $12 million Series A round closed in April 2025 included Suzano, the Brazilian forestry giant and the world’s largest market pulp producer [Global Venturing]. Having a strategic investor that controls the upstream feedstock,cellulose,is a significant moat. It’s a vertical integration play at the raw material level, ensuring both supply and a deep partner for tuning the slurry’s recipe.
The company’s disclosed funding to date totals approximately $16.1 million across three rounds, including a $3.5 million seed led by At One Ventures in 2022 [PR Newswire, June 2022][StartupIntros].

The competitive landscape
Simplifyber operates in the emerging field of next-generation, low-impact fibers, but its one-step molding process sets it apart from most peers. Its most direct competitors are other companies commercializing cellulose-based textiles, though their manufacturing approaches differ.
| Company | Material Source | Core Process | Primary Output |
|---|---|---|---|
| Simplifyber | Wood pulp, recycled textiles | 3D molding from cellulose slurry | Finished soft goods (uppers, panels) |
| Spinnova | Wood pulp, agricultural waste | Mechanical fibrillation into fiber | Fiber for spinning into yarn |
| Renewcell | Recycled cotton textiles | Dissolving pulp into Circulose® | Fiber for spinning into yarn |
While Spinnova and Renewcell produce a fiber that must then be spun, woven, and cut, Simplifyber aims to deliver a finished component. This is both its potential advantage,eliminating multiple cost and waste centers,and its scaling challenge, as it must build or retrofit an entirely new type of manufacturing line.
Where the wheels could come off
Any hardware-heavy, materials-science startup faces a steep climb. For Simplifyber, the path to mass production is lined with specific, capital-intensive hurdles.
- Production scaling. The company states a goal of reaching mass production within six years [sdgs.un.org, 2026]. Moving from fashion-week prototypes and pilot projects to high-volume, consistent output is a monumental engineering and financing challenge.
- Cost parity. The technology must achieve its stated aim of cost-competitiveness with polyester and other synthetic fibers to be adopted beyond niche, sustainability-premium products [Perplexity Sonar Pro Brief]. The economics of the slurry recipe and molding efficiency will be decisive.
- Industry adoption. Fashion supply chains are notoriously inertial. Convincing major brands to redesign products around a new molding paradigm requires more than a lower footprint; it requires proven performance, durability, and a reliable supply.
The company’s answer to these risks appears to be a focus on deep partnerships, like the one with Suzano, and a staged approach that starts with discrete components (like shoe uppers) before attempting to remake an entire garment.
The next twelve months
Simplifyber has said it will begin early pilot production later this year [sdgs.un.org, 2026]. The next year will be about moving from the lab and design collaborations into operational pilots. Key milestones to watch will be the announcement of a production partner or facility, the naming of its first major brand customer beyond a design collaboration, and concrete data on production costs and throughput.
On a unit basis, the potential is stark. If a single molded shoe upper avoids the 15% fabric waste from cutting a pattern, and uses 95% less water in dyeing, the environmental math starts to look compelling even before accounting for biodegradability. The real test is whether that math can also close on price. To win, Simplifyber doesn’t just have to beat other sustainable fibers; it has to beat the entire incumbent system of fabric mills, cut-and-sew factories, and the global logistics that connect them. That’s a taller order than making a beautiful shoe, but it’s the only one that changes the industry’s footprint.
